If I were still dealing with infertility (I'm much older now, and at a different place in my life), I would have found this post rather offensive. I am an agnostic, a CANNOT "just believe" and even if I were a believer, I would not be able to believe in a deity that was so cruel as to give babies to some who abuse and kill their children, while withholding them from parents who would be loving, caring parents. God has nothing to do with it.
As an agnostic, married to an atheist, I still managed, with the help of my infertility doctor, to conceive and maintain one pregnancy, my very dear son.
I wish all who are trying to conceive, whatever your belief system, the very best, but remember -- it isn't a matter of fault, blame, action or inaction (well, okay, other than the obvious! Certain actions are kind of required.... ;-)) Even for the normal fertile population, there is only a 20% chance per cycle.
I'm pulling for you!
